‘Hlavsa worked in the field of graphic design for more than sixty years, creating about 2000 book designs, through which he formed distinctly new visual and communicative values of typeface and markedly influenced the vision of the intellectual and artistic concept of the book. Hlavsa focused his artistic efforts on the book, regarding it as a means of communication, an individual work of art that makes a complex impression. It combines ideas, esthetic perception, and demands the reader’s interaction. On the one hand, Hlavsa’s conception of (typo)graphic design continues the tradition of the classic Czech typography of Karel Dyrynk, Oldřich Menhart or Method Kaláb; on the other hand, it simultaneously follows the Czech avant-garde, i. e. the work of Karel Teige and Ladislav Sutnar. However, the constructional and functional elements get a new content in Hlavsa’s typographic work: above all, Hlavsa brings a very distinctive artistic approach which always constructs a book or a periodical as a deliberate and compact structure.’
